When it comes to etiquette, manners and overall good behavior, even celebrities need help navigating the rough waters of stardom! It’s a good thingCountess LuAnn de Lesseps of The Real Housewives of New York City is joining forces with OK! to school them on the right thing to do! In a rough situation, we just ask, “What would the countess do?” This week, the countess chimes in on Charlie Sheen's apology and Christie Brinkley fighting with ex Peter Cook in the media.

Charlie Sheen was on the Today show where he apologized to America for his out-of-control behavior that happened last year. Do you think that apologizing is the right move to take or should Charlie just keep quiet and move on with his life?

Charlie Sheen made the right move by apologizing for his outrageous behavior, but time will tell if he’s reformed or just saying what he needs to say to work again. Since Charlie’s meltdown was so public, I think he’s right to reassure his fans that he’s got his act together and is excited to star in the new sitcom Anger Management. Charlie’s father, Martin Sheen, has agreed to guest star on his new show, which tells me more about Charlie’s mental health than just his words.

Tip: When you are given a second chance, take the opportunity seriously and do everything you can to succeed.

Both Christie Brinkley and Peter Cook appeared at different times this week on Today in a war of words against each other about their nasty divorce. Should they have kept their sparring private or is it okay to air their grievances in the media? What advice can you give for ending an ongoing fight?

I don't think Peter or Christie should air their differences on the Today show. Instead of sparring in public, they should work things out in private for the sake of their kids. The first step in resolving an ongoing conflict is to take a break from the fighting so that you can calm down and get a perspective on the situation.

Tip: Sometimes you have to agree to disagree in order to move forward.
